Hello, I'm happy to answer your questions. According to the knowledge I've learned from the web novels, the realm and level of a million skill points are usually set by the author himself. Different authors might have different ways of setting it. Some authors might divide the realms according to the difficulty or effect of the skills. For example, they would divide the skills into beginner, beginner, intermediate, advanced, and so on. The divine patterns might be divided into different symbols, each of which had different attributes and abilities. Other authors might divide the levels according to the application of the skills, such as dividing the skills into offensive, defensive, auxiliary, etc., while the divine patterns might be divided into different elements, each of which had different attributes and abilities. The specific division depends on the author's setting. We can pay attention to the author's setting in order to better understand the plot and characters of the novel.
